Hi,
Im using 1.10.4 and im facing the following problem.
In advanced search, i add (Add other field dropdown) the field "Closed" and then i select "between". Then I press on the date fields to display the calendar popup and select dates. If i press on a specific date in the calendar, the popup disappears but no date is inserted in the fields. I also noticed that if i press on the arrows to select previous/next month, year goes to 1900.
Now If i continue with search and get no results and then go back to advanced search and press on text "between and " of the same field (closed), date fields work fine. The "created" field witch is by default on the search page, works fine.
